On "Brain of Britain" on the radio today, a contestant was asked for the adjective meaning "uncompromisingly honest or just" which is derived from the name of one of the sons of Zeus.
Pause. Then the chap said drily, "Frank."
I love it. So much better an answer than the actual one, which is "rhadamanthine" from Rhadamanthus. Never heard of him. Heard of Frank, though.
